LoadLibrary problem

[Dimitrie O. Paun]

Hi guys,

I'm back from my vacation! :)

Before I left I had problems running visual-mingw when built as a 
Winelib app. This is a C++ app and needs the wrapper idea to work.
In other words the main app is in a dll names 
'visual-mingw-wrap.dll.so' (I've added the 'wrap' in the name to
avoid potential confusion, and to make it easier to search for it).

The wrapper simply does a LoadLibrary for this DLL, and this
LoadLibrary call fails. Here is the relevant part of a
    --debugmsg +module,+server

Any ideas?

This is correct, Wine finds the file correctly.

trace:module:PE_LoadImage Trying to create section...

Here, we're executing this (which fails):

TRACE( "Trying to create section...\n" );
    if (NtCreateSection( &mapping,
                         STANDARD_RIGHTS_REQUIRED | SECTION_QUERY | SECTION_MAP_READ,

LoadLibrary doesn't support loading a .so directly at this point. You
need to pass it the .dll name and make sure the corresponding .so can
be found somewhere in WINEDLLPATH. Or you need to add .so support to
LoadLibrary...

Indeed, that was a left-over from some experiments I was doing before
I left for vacation. Now, the LoadLibrary call is actually for 
"visual-mingw-wrap.dll". It still doesn't work, I get for
    bin/visual-mingw --debugmsg +module,+server
the following trace:

And yes, WINEDLLPATH points to the right dir. Look:
